Join Matt Brill, founder of Bauen Build, for our October Project of the Month as he shares practical, on-the-ground strategies for getting Passive House air sealing and ventilation right the first time. He is joined by 475.Supply’s ventilation specialist Gabrielle O’Grady to offer insights on health and indoor air quality that are essential to communicate to your clients. From airtightness testing breakthroughs to step-by-step field tactics, Matt will walk through how Bauen’s team approaches precision and durability on every jobsite. Whether you are a builder, architect, or consultant, you will leave with actionable insights to strengthen your own process and perhaps a new way of thinking about the details that make or break high performance homes.

Learning Objectives

• Identify key air sealing details and common failure points that impact Passive House airtightness, and explain strategies to address them effectively during construction.

• Evaluate the role of balanced ventilation systems (ERV/HRV) in Passive House projects, including best practices for design integration and on-site installation.

• Apply practical jobsite methods—such as sequencing, mock-ups, and airtightness testing—to ensure high-performance outcomes and minimize costly rework.

• Analyze case study results to understand how precise air sealing and ventilation decisions contribute to occupant comfort, durability, and long-term energy performance.

This free presentation will take place on Wednesday, October 15th at 9am PT / 12pm ET and will be followed by a lively Q+A session. Don't miss this opportunity to learn from industry leaders and engage with the PHA community. See you there!
